Quillon, an AI platform focused on technical accounting and financial reporting, has raised $1.5 million in a pre-seed round led by 42CAP, with participation from angel investors linked to NVIDIA and Roblox.
The company also announced its rebrand from Acclara AI as it develops tools designed to bring audit-grade reliability to complex accounting workflows.
What The Company Does
Founded in 2023 by Nikolay Dakov, Ivaylo Stefanov, and Atanas Dobrev, Quillon operates between Sofia and San Francisco. The company builds AI systems for technical accounting, a discipline that involves interpreting accounting standards and producing structured memos used in high-stakes financial reporting.
These workflows underpin decisions in areas such as revenue recognition, mergers, restructurings, and regulatory filings. Because they are reviewed by auditors and sometimes regulators like the SEC, accuracy and traceability are critical, and errors can have significant financial and compliance consequences.
Quillon’s platform is built around a proprietary knowledge graph of accounting standards integrated with financial filing data. It breaks down accounting questions into structured steps, linking each conclusion directly to source material. The system combines research, contract analysis, benchmarking, and memo generation in a single workflow, while allowing accountants to review and validate each stage.

Market context / industry background
Accounting teams are increasingly under pressure to handle more complex reporting requirements with limited capacity. General-purpose AI tools are being used to accelerate workflows, but they often lack verifiability, can produce unsupported claims, and struggle to maintain clear links to authoritative accounting standards.
This gap is particularly important in regulated financial environments, where outputs must be defensible under audit and fully traceable to official sources. As reporting complexity increases, demand is rising for domain-specific systems that combine automation with auditability rather than replacing human oversight.
In addition, regulatory frameworks such as IFRS and GAAP continue to evolve, adding further layers of complexity to financial reporting processes across jurisdictions. Companies operating internationally must reconcile differing standards, currency effects, and disclosure requirements, which increases both workload and risk of error. At the same time, audit firms are placing greater emphasis on data lineage and documentation quality, requiring accounting systems to provide transparent, step-by-step justification for every adjustment or classification. This is driving adoption of tools that embed compliance logic directly into workflows, rather than treating it as a separate post-processing step. Over time, this shift is expected to redefine how financial reporting systems are designed and validated globally today now.
Founder / investor commentary
“For two years we’ve watched technical accountants try to use general-purpose AI to keep up with a workload that has outpaced hiring,” said co-founder and CEO Nikolay Dakov.
“They couldn’t, because no auditor will defend output that the AI cannot cite. We built Quillon to close that gap: a workspace where the AI does the analysis, the accountant drives every step, and every claim traces back to the exact paragraph in the standards.”
Growth plans / use of funds
Quillon is initially focused on automating technical accounting memos, which form the foundation of financial reporting for public companies. The longer-term plan is to expand into broader reporting workflows, including quarterly and annual disclosures.
The new capital will be used to expand engineering capacity and build out go-to-market teams, as the company transitions from an early research product into a platform capable of supporting end-to-end accounting workflows.
